My thoughts: parents must impart Christianity and Christian values to their children by teaching, loving, modeling Christ in the home and discipline. The Holy Spirit must also work. Veggie Tales is entertainment. Any parent expecting anything more is, well....
And that is of course correct.
I think the deeper point that the author makes is in America there is a lack of a true understanding of what Christ did for us.
Can Veggie Tales be useful? Sure.
Is it?
I'll bet there are tons of teens and 20 somethings whose sole knowledge of Scripture is based on Veggie Tales.
And I'm still waiting for my water buffalo.
